...Each iPhone 5, for instance, contains $1.58 of gold,
$.36 of silver, $.05 of platinum, and $.12 of copper.

Those numbers may sound small, but the phone holds from six to 300
times more precious metal than the equivalent amount of ore from a mine.

Also, in addition to the more familiar precious metals, smartphones
also contain traces of huge swaths of the periodic table, particularly
those “rare earths” that today’s electronics so depend on: Yttrium,
Lanthanum, Neodymium, Gadolinium, and Europium, among others.
